🙋 Introduction

The scroll-margin-bottom property in CSS is used to set the bottom margin of an element that snaps into a scroll container.

This property is part of the CSS Scroll Snap Module, which allows web developers to control the snap position of elements when the user scrolls. By using scroll-margin-bottom, you can adjust the position of an element to be a certain distance away from the container's bottom edge when it snaps into place.

💡 Syntax

The syntax for the scroll-margin-bottom property is straightforward and allows you to specify a length value.

  scroll-margin-bottom: value;
}

Here, value can be any valid CSS length unit such as px, em, rem, %, etc.
